<div class="field field-name-comment-body field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even" property="content:encoded"><p>Why are you using different host files (machine file in your case) for sockets vs. InfiniBand*? You should use the same host file for either fabric. The ranks are initially launched over sockets using SSH. Once the ranks are started, they will connect over the selected fabric. Try using the same host file and see if that changes anything.</p>
<p>I'm also curious why there is no indication of trying the ofa-v2-mlx4_0-1 provider. Try setting I_MPI_DAPL_PROVIDER=ofa-v2-mlx4_0-1u and send the debug output again. For now, setting I_MPI_DEBUG=5 is sufficient for the information needed. If necessary, we'll try a higher debug level later, but it's pretty rare that anything over 5 is needed.</p>
